Personally, I'm only concerned about my IP address since I never linked an email to my account. But honestly, I'm more worried about the possibility of this forum being hacked beyond recovery. At this point, though, all we can do is trust the Bitcointalk team as I believe they're competent enough to prevent future attacks.

Think about it... most hackers target crypto directly. Why would they attack an educational forum that helps grow the ecosystem? They benefit more when new investors enter the market (thanks to learning here) because increased exchange volume creates bigger targets for their exploits.
